Logans Labs test now what?

10 years ago

Hi there,

i have enjoyed the knowledge of this forum for the past few months in preparation for trying to change our lawn for the better. It was in rough shape, but for the past 2 days we thatched, seeded and starter fertilized bare spots from this summer's drought to get things moving in the right direction.

Also in preparation I had soil samples analyzed at Logan Labs, per the recommendation here, and discovered some startling results. I am posting the 2 reports here that detail recommendated amendments. Can anyone please help translate this into what fertilizer/products to use?


Logan Labs report 1

Report 2


Thank you in advance,

Brad

    Morpheus will be along to read them for you.......trust his recommendations, they have worked for me!

    It's always fun to see the recommendations sheet. They're far more aggressive than I would ever be.

    I'll presume FRY is Front Yard, BY is Back Yard. If, instead, those are initials of two separate people...well, it doesn't matter, but my recommendations might not make the most logical sense in English that way. :-)

    Sample Depth 6, 3: If these are very different crops (lawn and garden respectively), please let me know. I'm doing the read for lawn, and adjusting everything to four inches in the few places where I need to do that.

    ME, high 8's: A nice place to be, the soil holds tolerable levels of resources. If you made me guess, I'd say sand with reasonable amounts of silt.

    pH 5.9, 5.1: A little low and quite low, respectively. We'll fix this under calcium, mostly, with a nod to magnesium and potassium. I'd definitely like to move the front into a more optimal position, and the back has to adjust a fair bit.

    Organic Matter 4-ish: Certainly always mulch mow and mow your fall leaves in, but you don't need to make any special effort here. Higher OM does help with water retention and make your pH matter a bit less, though, so that always helps.

    Sulfur 10, 17: Both normal answers with tons of room to play.

    Phosphorus 31, 13 (20, 17 adjusted): Both very low for any purpose...borderline deficient, actually. My target here would be 200 for both areas, and we use standard starter fertilizer to adjust this. Just get the cheapest, they're all the same.

    Calcium 63%, 31%: OK, but I'd like to adjust the front. The back needs help. For this, we use Encap, Mag-I-Cal, or Pennington Fast Lime to add calcium only and avoid adding elements I don't want via the lime. They're also ground finer and work faster than standard limes.

    Magnesium 10%, 15%: Both are fine, and both are actually near optimal. While I might-could tap the front, I'm not inclined to do so at this time.

    Potassium 1.9%, 2.4%: Both are a bit low. Although I could theoretically ignore the back, I'd rather not. We use potassium sulfate to adjust this, available from--or they can order it for you--landscape and garden shops. Or online.

    Minor Elements:

    Boron 0.66, 0.22: The recommendations from Logan flat out scare me, and please ignore their recommendation of 0.4 pounds of Solubor per K. I'd rather be much more gentle. While not the most important element, I'll always work to move your lawn into the most optimal range on everything. Me? I'd fix this. We use Milorganite as a carrier and 20 Mule Team Borax as the boron source. You can purchase 20 Mules at the grocery store in the laundry section. In a wheelbarrow or the like, dump the Milo. Spraying very, very lightly with water (I use a spray bottle like the kind people use to damp their clothes when they iron) will help the boron stick. Add the recommended amount of 20 Mule Team Borax and stir, spraying occasionally to get the stuff to stick to the Milo. Then apply over the recommended area. So if going for bag rate Milorganite (1 bag per 2,500 square feet), you'd add 10 tablespoons of 20 Mule Team Borax.

    Zinc: I could tap this, but you have enough to do. Let's let it ride.

    Recommendations, rest of fall:

    October 1: Apply starter fertilizer at bag rate.

    October 15: Apply 3 pounds per thousand square feet of Encap, Mag-I-Cal, or Pennington Fast Lime in the front. Apply 9 pounds per thousand square feet of Encap, Mag-I-Cal, or Pennington Fast Lime in the back.

    November 1: Apply 3 pounds per thousand square feet of potassium sulfate to the front and back.

    2017 Recommendations:

    April 1: Apply 4 tablespoons per thousand square feet of 20 Mule Team Borax in Milorganite carrier.

    April 15: Apply 2 pounds per thousand square feet of Encap, Mag-I-Cal, or Pennington Fast Lime in the front. Apply 9 pounds per thousand square feet of Encap, Mag-I-Cal, or Pennington Fast Lime in the back.

    April 25: Apply starter fertilizer at bag rate. This is a technical error, but your low phosphorus is more problematic than applying a little nitrogen at the wrong time.

    May 1: (Front Only) Apply 3 pounds per thousand square feet of potassium sulfate to the front only.

    Memorial Day: Apply starter fertilizer at bag rate.

    Labor Day: Apply starter fertilizer at bag rate.

    October 1: Apply starter fertilizer at bag rate.

    I'm very grateful for your reply. I purchased the recommended supplies, followed the first recommendation and am on my way to bringing this lawn back to life!

    @dchall_san_antonio I was startled because the lawn was green, was growing and appeared healthy. But now that I've done more research I'm beginning to realize how much better it could be. I spot treated weeds for hours all spring and summer. There are bare spots throughout. And the biggest pet peeve I have is the variation of grasses- I'm talking patches, not intermixed species.

    I thought I'd share a report since my lawn has improved significantly, in most places, after following "the plan" since last fall.

    I added prodinium in early April, which I hope doesn't deviate from the plan @morpheuspa provided. I also have been using Ortho directly on weeds.

    My current step is potassium sulfate. I'm assuming that it's best to mix that in with a carrier?

    Overall, I'm really excited how this is going! And I appreciate the resource that this forum offers along this journey.

    Potassium sulfate comes in a pelleted form that can be spread like any fertilizer.

    Look at kelp 4 less, best price there and as Ridgerunner says, its granular, just measure out the pound per square feet
